PROPERTIES

• VISCOSITY

  • How EASILY a fluid FLOWS (the THICKNESS)
  • HIGH viscosity- fluid flows SLOWLY
  • Size of hydrocarbon INCREASES, molecules get more VISCOUS
  • LONG chain hydrocarbon- flows SLOWLY (extremely viscous)
• FLAMMABILITY?

  • How easily it BURNS (COMBUSTS)
  • SHORT chain- extremely FLAMMABLE
  • Size of molecule INCREASES, less FLAMMABLE
  • Molecules with long chains are DIFFICULT to BURN
• BOILING POINT

  • TEMPERATURE at which a LIQUID turns into a GAS
  • Short chain- LOW bp
  • MEPB are GASES at room temperature (lower B.P than room temp)
  • Size of molecule increases, b.p INCREASES
  • Long chain- HIGH b.p
• VOLATILITY:

  • TENDENCY to turn into a GAS
  • EVAPORATE more easily due to its LOW b.p
